Abstract: In some embodiments, a network node (e.g., a base station) collects information pertaining to components that form a Maximum Received Timing Difference (MRTD). For instance, the network node determines TAE. The network node then evaluates, for a particular UE, whether a certain MRTD requirement (MRTDR) for a specific coordinated service (CS) can be fulfilled. If the requirement can be met, then the network node may initiate the specific CS for the UE (or continue providing the CS), and if the requirement cannot be met, then the network node may stop or modify the CS for the UE.

Abstract: A receiver (10) featuring a distributed antenna combining system performs two stages of antenna combining. An antenna array (30) receives (102) L streams, or information flows, from UEs (20), and outputs antenna signals on N antenna ports. N parallel radio receivers (40) frequency convert (104) the N received signals to baseband. A first antenna combining circuit (50) applies (106) a relatively low-complexity form of antenna combining (e.g., MRC) to the N radio signals to generate K streams of virtual information. A second antenna combining circuit (60) applies (108) a relative high-complexity form of antenna combining (e.g., IRC) to the K virtual streams to generate L information streams. In one embodiment, antenna elements may have different polarization directions, and the first antenna combining circuit (50) generates two, differently-polarized virtual information streams for each UE (20) stream.

Abstract: According to an aspect, a wireless device receives, from a first node, a blacklist with random access response identifiers. The wireless device transmits a random access preamble to initiate random access to another node and receives a random access response. The wireless device compares a random access response identifier included in the received random access response to the random access response identifiers in the blacklist and establishes a connection to a second node that corresponds to the received random access response, responsive to determining that the random access response identifier in the received random access response is not included in the blacklist. The wireless device sends, to the second node, an identifier for the first node or an identifier for a beam transmitted by the first node, or both.
